Title: Signature electronique
Hi JF Le Fillâtre,
Hello,
You cannot. As the message said, you cannot change the stripe count.
I don't change the strip count, the number is the same.
So
you can add 4 bricks and you have a distributed + striped volume, but
you cannot change the stripe count by re-adding existing bricks into the
volume with a different stripe count, or by adding an additional brick
to the volume.
That is the real question : "is it possible to add a node to a stripe volume one by one ?"
I not when I receive a new node I can't insert it in the global cluster service !
Your email isn't very clear; could you please send:
- the list of commands in the order that you typed them;
- the output of "gluster volume info" and "gluster volume status"
On one of the four node :
[root@boogy2 ~]# gluster volume stop gvHome
on the new node :
[root@moody gvHome]# gluster volume add-brick gvHome moody:/mnt/gvHome/brick1
volume add-brick: failed: Incorrect number of bricks supplied 1 with count 2
[root@boogy2 ~]# gluster volume info gvHome
